Description

Technical Field

[0001] The present application relates to the technical field of gas purification, and in particular to a gas scrubbing tank for gas purification. Background Art

[0002] In the existing water electrolysis process, after the electrolysis of water in the electrolysis equipment is completed, the gas is discharged together with the waste liquid to form a gas carrying the waste liquid. At this time, it is necessary to use the gas purification system in the electrolysis equipment to purify the discharged gas.

[0003] At present, common gas purification systems mainly use gas-liquid separation equipment. After the gas is discharged into the gas-liquid separation equipment, the gas is separated from the waste liquid to achieve gas purification. However, after the gas carrying the waste liquid passes through the gas-liquid separation equipment, the separated gas needs to be washed by a washing device. The separated waste liquid needs to be returned to the electrolysis equipment for reuse. However, since the electrolysis of water requires water consumption, the water content of the waste liquid is reduced, which will cause the concentration of the waste liquid to change. In addition, water needs to be added to ensure that the concentration of the waste liquid remains stable. At the same time, the water is also added to replenish the consumed water to ensure that there is enough water for electrolysis. This requires the use of water replenishment equipment to replenish water in the reflux waste liquid.

[0004] This means that in addition to the gas-liquid separation equipment, the gas purification system also needs additional washing equipment and water replenishment equipment to further process the gas and waste liquid. This means that the gas purification system has more components and the equipment cost of the gas purification system is higher. Summary of the invention

[0005] The present application provides a gas scrubbing tank for gas purification, the purpose of which is to simultaneously realize the three functions of gas-liquid separation, gas scrubbing and water replenishment through the gas scrubbing tank, so that the gas scrubbing tank can be used as a gas-liquid separation device, a gas scrubbing device and a water replenishment device at the same time, which can reduce the equipment cost of the gas purification system.

[0006] The present application provides a gas scrubbing tank for gas purification using the following technical solution: A gas washing tank for gas purification comprises a tank body, on which a gas inlet, a gas outlet, a water replenishment inlet and a waste liquid outlet are provided; a gas pipe is also provided in the tank body, one end of the gas pipe is connected to the inner wall of the tank body, and the other end is closed, and the gas pipe is communicated with the gas inlet, and a plurality of micropores are provided on the outer wall of the gas pipe; a water replenishment pipe is also provided in the tank body, one end of the water replenishment pipe is connected to the inner wall of the tank body, and the other end is closed, and the water replenishment pipe is communicated with the water replenishment inlet, and a spray assembly is provided on the water replenishment pipe, and the spray assembly is located on the upper side of the gas pipe in the vertical direction.

[0007] By adopting the above technical solution, firstly, a gas inlet is provided on the tank body, so that the gas of the waste liquid to be separated can be input into the tank body. A gas pipe is provided in the tank body, and the gas pipe is connected to the gas inlet. A plurality of micropores are provided on the gas pipe. The micropores are provided so that the gas can be discharged from the gas pipe through the micropores, while the waste liquid remains in the gas pipe, so that the preliminary separation of gas and liquid can be achieved.

[0008] On this basis, since a gas outlet is provided on the tank body, the separated gas can be discharged, thereby satisfying the function of gas-liquid separation.

[0009] Secondly, a water replenishment inlet is provided on the tank body, so that room-temperature pure water can be input into the tank body for water replenishment. A water replenishment pipe and a spray assembly are provided in the tank body, and the water replenishment pipe is connected to the water replenishment inlet, and the spray assembly is connected to the water replenishment pipe, so that the room-temperature pure water input into the tank body will be input into the spray assembly through the water replenishment pipe, and the spray assembly will spray out the room-temperature pure water. Since the spray assembly is located on the upper side of the gas pipe, the gas discharged from the gas pipe will rise toward the direction of the spray assembly. On the contrary, the room-temperature pure water sprayed from the spray assembly will naturally fall toward the direction of the gas pipe. In this process, the gas contacts the room-temperature pure water in countercurrent, and the room-temperature pure water washes the gas and removes the waste liquid. This can meet the function of gas washing.

[0010] On this basis, since the tank body is provided with a waste liquid outlet, the room temperature pure water after cleaning the gas can be discharged from the waste liquid outlet. At this time, the room temperature pure water is mixed with a part of the waste liquid, which makes the discharged room temperature pure water able to flow back into the electrolysis equipment. On the one hand, the waste liquid can be refluxed to reduce the consumption of waste liquid; on the other hand, the consumed water can be replenished to ensure the concentration and water volume of the waste liquid.

[0011] Therefore, through the cooperation of the tank body, gas pipe, water supply pipe and spray assembly, the three functions of gas washing, gas washing and water supply can be achieved. This makes the gas washing tank of the present application able to be used as a gas-liquid separation equipment, gas washing equipment and water supply equipment at the same time, which can reduce the equipment cost of the gas purification system.

[0012] Optionally, a washing disc is further provided in the tank body, a washing tank is provided on the upper side of the washing disc, the gas pipe is connected to the washing disc, and one end of the gas pipe extends into the washing tank.

[0013] By adopting the above technical solution, a washing trough is provided on the washing disc, and one end of the gas pipe extends into the washing trough. Since the washing trough on the washing disc has the function of storing water, when the spray assembly on the upper side of the gas pipe is working, the spray assembly will spray normal temperature pure water into the washing trough. At this time, part of the normal temperature pure water can be stored in the washing trough, and the normal temperature pure water will flood the gas pipe. Based on such a structural setting, when the gas pipe discharges gas, the gas will directly enter the normal temperature pure water stored in the washing trough, which will form tiny gas microbubbles in the normal temperature pure water, thereby increasing the contact area between the gas and the normal temperature pure water and improving the washing effect of the gas.

[0014] Optionally, a drainage hole is provided on the side wall of the washing tray, and the drainage hole is connected to the washing tank.

[0015] By adopting the above technical solution, the drainage hole is opened. After some room temperature pure water is stored in the washing tray, the drainage hole can discharge the used room temperature pure water out of the washing tank, so that the used room temperature pure water can flow into the tank body, thereby realizing the collection of used room temperature pure water.

[0016] Optionally, a jacketed plate is further provided in the tank body, and overflow plates are provided on opposite sides of the jacketed plate; a jacketed groove is provided on the upper side of the jacketed plate, the jacketed groove penetrates the jacketed plate along the spacing direction of the two overflow plates, and the overflow plate closes the side corresponding to the jacketed groove; the washing plate is arranged in the jacketed groove, and the drain hole is connected to the jacket groove, and the upper side of the overflow plate is located above the drain hole.

[0017] By adopting the above technical solution, a jacket groove is provided on the jacket disc, and the jacket groove realizes the installation of the washing disc. The overflow plate is arranged so that a water storage layer capable of storing room temperature pure water is formed between the overflow plate facing the side wall of the washing disc, the two inner side walls of the jacket groove and the side wall corresponding to the washing disc, wherein the overflow plate is arranged to limit the height of the liquid level in the water storage layer. When the spray assembly continues to work, the liquid level in the water storage layer gradually increases. When the liquid level exceeds the upper side of the overflow plate, the excess room temperature pure water overflows into the tank body.

[0018] By such a structural arrangement, a room temperature pure water pool with a constant liquid level can be formed in the washing disk and the jacket disk, which can ensure that the gas discharged from the gas pipe will always pass through the room temperature pure water pool with a constant liquid level, which keeps the gas pressure stable and the washing effect can also be kept stable. Since the gas washing tank of the present application is used to treat the gas discharged from the electrolysis of water, the balance of the gas pressure is very important, because the gas and oxygen in the electrolysis equipment are separated by a diaphragm, and the pressure difference on both sides of the diaphragm needs to be controlled to be stable to avoid the increase of oxygen content in the gas due to the pressure difference of the diaphragm.

[0019] Optionally, a plurality of combing grooves are formed on a side of the overflow plate facing the washing disk, the combing grooves penetrate the washing disk, and the plurality of combing grooves are sequentially spaced apart along the width direction of the jacket groove.

[0020] By adopting the above technical solution, the comb groove is opened, so that when the liquid level in the water storage interlayer exceeds the bottom of the comb groove, the room temperature pure water can overflow into the tank body through the comb groove. Since a plurality of comb grooves are arranged in sequence along the width direction of the jacket groove, the overflow plate has a comb-shaped structure, which enables the room temperature pure water in the water storage interlayer to be quickly replaced and evenly overflow into the tank body.

[0021] Optionally, the spray assembly includes a plurality of spray pipes, which are arranged in sequence at intervals along the length direction of the water supply pipe and are arranged parallel to each other, and the spray pipes are connected to the water supply pipe; a plurality of nozzles are arranged on the lower side of the spray pipe, which are arranged in sequence at intervals along the length direction of the corresponding spray pipe.

[0022] By adopting the above technical solution, the spray assembly can evenly spray room temperature pure water onto the gas pipe through the setting of several spray pipes and several spray heads, thereby improving the uniformity of contact between the gas discharged from the gas pipe and the room temperature pure water, ensuring consistent washing effect of the gas at various locations.

[0023] Optionally, the gas pipe is made of silicon carbide material.

[0024] By adopting the above technical solution, since the gas pipe is made of silicon carbide material, the gas pipe has good strength. At the same time, after the gas pipe separates the gas and the waste liquid, the gas pipe made of silicon carbide can penetrate the waste liquid out of the gas pipe, so after the gas washing is completed, the remaining waste liquid can also be discharged into the tank body.

[0025] Optionally, the tank body is also provided with a waste liquid inlet.

[0026] By adopting the above technical solution, the waste liquid inlet is opened, so that the gas discharged from the electrolytic equipment and the waste liquid settled in the waste liquid can be directly discharged into the tank body, and the small amount of gas contained in the waste liquid entering the tank body can automatically overflow, which can achieve the separation of gas in the waste liquid.

[0027] Optionally, the tank body is also provided with a waste liquid replenishment inlet.

[0028] By adopting the above technical solution, the waste liquid replenishing inlet is opened, and waste liquid can be added into the tank body to adjust the concentration of the waste liquid so that the concentration of the waste liquid meets the requirements of reuse.

[0029] Optionally, a liquid level meter is provided in the tank body.

[0030] By adopting the above technical solution, the liquid level component is used to detect the height of the mixed liquid of the waste liquid and the room temperature pure water in the tank body, so as to facilitate the timely discharge of the waste liquid.

[0031] In summary, the present application includes at least one of the following beneficial technical effects: 1. The present application can realize the three functions of gas-liquid separation, gas washing and water replenishment through the coordination of the tank body, gas pipe, water replenishment pipe and spray assembly. This makes the gas washing tank of the present application able to be used as a gas-liquid separation device, a gas washing device and a water replenishment device at the same time, which can reduce the equipment cost of the gas purification system.

[0032] 2. Through the setting of the washing disk, the present application allows the gas to directly enter the room temperature pure water stored in the washing tank when the gas is discharged from the gas pipe. This will form tiny gas microbubbles in the room temperature pure water, thereby increasing the contact area between the gas and the room temperature pure water and improving the washing effect of the gas.

[0033] 3. The present application, through the provision of a jacketed disc, can form a room temperature pure water pool with a constant liquid level inside the washing disc and the jacketed disc, which can ensure that the gas discharged from the gas pipe will always pass through the room temperature pure water pool with a constant liquid level, thereby keeping the gas pressure stable and the washing effect can also be kept stable.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0039] A gas scrubbing tank for gas purification, referring to Figure 1, comprising a tank body 1, the tank body 1 is axially arranged in a horizontal direction, two brackets are arranged on the lower side of the tank body 1, and the two brackets are spaced apart along the axial direction of the tank body 1.

[0040] Reference Figure 1 and Figure 2 A gas inlet 11 is provided at one axial end of the tank body 1, and a gas outlet 12 is provided on the upper side of the tank body 1. The gas of the waste liquid to be separated can be introduced into the tank body 1 through the gas inlet 11, and the gas outlet 12 discharges the separated and washed gas.

[0041] Reference Figure 2 and Figure 3 A washing disc 2 is arranged in the tank body 1, and the bottom of the washing disc 2 is connected to the inner wall of the tank body 1. A gas pipe 3 is arranged between the washing disc 2 and the inner wall of the tank body 1, one end of the gas pipe 3 is connected to the inner wall of the tank body 1, and the other end is connected to the washing disc 2, and one end of the gas pipe 3 is connected to the gas inlet 11, and the other end is closed, and a plurality of micropores are opened on the gas pipe 3. In this embodiment, the gas pipe 3 is made of silicon carbide, and the diameter of the micropores opened on the gas pipe 3 is 3 microns.

[0042] The gas of the waste liquid to be separated is discharged into the gas pipe 3 through the gas inlet 11, and then the gas can be discharged from the gas pipe 3 through the micropores on the gas pipe 3. In addition, since the gas pipe 3 is made of silicon carbide, the diameter of the micropores opened on the gas pipe 3 is 3 microns, and the pore size of 3 microns ensures that the gas can pass through, while the waste liquid carried in the gas cannot pass through, which can achieve preliminary separation of gas and liquid; and the intercepted waste liquid will penetrate from the bottom of the gas pipe 3 to the outside of the gas pipe 3, which can prevent the gas pipe 3 from being blocked by excessive waste liquid.

[0043] In this embodiment, the diameter of the gas pipe 3 is 5 cm, the wall thickness is 0.2 cm, the length is 50 cm to 100 cm, and the opening rate is greater than 70%. The structural setting and material selection of the gas pipe 3 ensure that the gas can be quickly discharged from the gas pipe 3, thereby improving the gas washing efficiency.

[0044] Reference Figure 2 and Figure 3 A water replenishment inlet 13 is provided at one end of the tank body 1 along its axial direction away from the gas inlet 11 . The water replenishment inlet 13 can be provided to replenish normal temperature pure water into the tank body 1 .

[0045] Reference Figure 2 and Figure 3 A water supply pipe 4 is also provided between the washing disk 2 and the inner wall of the tank body 1. The water supply pipe 4 is axially arranged along the axial direction of the tank body 1. One end of the water supply pipe 4 is connected to the inner wall of the tank body 1, and the other end is connected to the washing disk 2, and the water supply pipe 4 is connected to the water supply inlet 13.

[0046] Reference Figure 2 and Figure 3 The water supply pipe 4 is provided with a spray assembly 5, which includes a plurality of spray pipes 51, which are arranged in sequence and at intervals along the axial direction of the water supply pipe 4, and the axial direction of the spray pipe 51 is arranged in the horizontal direction, and the axial direction of the spray pipe 51 is arranged perpendicular to the axial direction of the water supply pipe 4, and the middle part of the spray pipe 51 is connected to the water supply pipe 4. The spray pipe 51 is arranged at intervals on the upper side of the gas pipe 3 in the vertical direction, and a plurality of nozzles 52 are arranged at the lower end of the spray pipe 51, and the plurality of nozzles 52 are arranged in sequence and at intervals along the axial direction of the spray pipe 51.

[0047] Reference Figure 2 and Figure 3 The water supply pipe 4 and the plurality of spray pipes 51 are all located on the upper side of the gas pipe 3 in the vertical direction. When the gas is discharged from the micropores on the gas pipe 3, normal temperature pure water is introduced into the water supply pipe 4, and the normal temperature pure water flows into the plurality of spray pipes 51 and is sprayed out through the corresponding nozzles 52. At this time, the gas discharged from the micropores on the gas pipe 3 moves upward, and the normal temperature pure water discharged from the nozzles 52 moves downward. The gas and the normal temperature pure water are in countercurrent contact. At this time, the gas is in full contact with the normal temperature pure water, thereby realizing the gas washing function.

[0048] Reference Figure 2 and Figure 3 A washing tank 21 is provided on the upper side of the washing tray 2 , one end of the gas pipe 3 and the water supply pipe 4 are extended into the washing tank 21 , and a plurality of spray pipes 51 are located in the washing tank 21 .

[0049] Since the washing tank 21 has the function of storing water, through the action of the spray component 5, some room temperature pure water can be stored in the washing tank 21, and then the room temperature pure water submerges the gas pipe 3, which makes the gas discharged from the gas pipe 3 directly enter the room temperature pure water to achieve gas washing.

[0050] Since the micropores on the gas pipe 3 of the present application are micrometer-level, gas microbubbles will be formed in the room temperature pure water when the gas is discharged from the gas pipe 3, which can increase the contact area between the gas and the room temperature pure water, thereby improving the washing effect of the gas. Specifically, in this embodiment, the gas microbubbles discharged into the washing disk 2 through the gas pipe 3 only need to stay in the washing tank 21 for no less than 1 second to effectively achieve aeration washing.

[0051] Reference Figure 2 and Figure 3 The length direction of the washing disk 2 is arranged along the axial direction of the tank body 1, and a plurality of drainage holes 22 are opened on both sides of the width direction of the washing disk 2. The plurality of drainage holes 22 are arranged in sequence along the length direction of the washing disk 2, and the drainage holes 22 are connected to the washing tank 21.

[0052] The opening of the drainage hole 22 allows the water in the washing tank 21 to flow into the tank body 1, thereby realizing the recovery and storage of room temperature pure water. Since room temperature pure water can replenish the consumed water for the electrolysis equipment, the waste liquid washed out of the gas can also be recovered.

[0053] Reference Figure 2 and Figure 3 A jacket plate 6 is also provided in the tank body 1, and a jacket groove 61 is provided on the upper side of the jacket plate 6. The jacket groove 61 penetrates the jacket plate 6 along the width direction of the washing plate 2. The washing plate 2 is arranged in the jacket groove 61, and the two opposite side walls of the washing plate 2 along its own length direction are respectively fixedly connected to the inner side walls corresponding to the jacket groove 61, and the plurality of drainage holes 22 are all connected to the jacket groove 61.

[0054] Reference Figure 3 Overflow plates 7 are provided on opposite sides of the jacket plate 6, and the two overflow plates 7 are arranged at intervals along the width direction of the washing plate 2. The length direction of the overflow plates 7 is arranged along the width direction of the jacket groove 61, and the two sides of the overflow plates 7 in the length direction are respectively connected to the inner side walls corresponding to the jacket groove 61, and one side of the overflow plate 7 in the width direction is connected to the groove bottom of the jacket groove 61, then a water storage interlayer 62 is formed between the overflow plate 7, the two opposite inner side walls of the jacket groove 61 and the washing plate 2, and a plurality of drainage holes 22 are connected to the corresponding water storage interlayer 62, and the upper side surface of the overflow plate 7 is located on the upper side of the drainage hole 22 in the vertical direction.

[0055] Reference Figure 3 The setting of the overflow plate 7 forms a water storage interlayer 62, so that room temperature pure water can be stored in the washing plate 2 and the jacket plate 6. When the liquid level of the room temperature pure water is higher than the height of the overflow plate 7, the room temperature pure water in the water storage interlayer 62 is discharged into the tank body 1, which can realize the collection of room temperature pure water. Since there is room temperature pure water with a constant liquid level in the washing plate 2, the gas discharged from the gas pipe 3 will always pass through the room temperature pure water with a constant height, which ensures the stability of the gas pressure and the stability of the washing effect. For electrolysis equipment, the stability of gas pressure is very important.

[0056] Reference Figure 3 A plurality of combing grooves 71 are formed on one side of the overflow plate 7 facing the washing dish 2 . The length direction of the combing grooves 71 is arranged in the vertical direction, and the upper ends of the combing grooves 71 penetrate the overflow plate 7 . The plurality of combing grooves 71 are evenly spaced in sequence along the length direction of the overflow plate 7 .

[0057] When the liquid level in the water storage interlayer 62 is higher than the bottom of the combing groove 71, the room temperature pure water in the water storage interlayer 62 will be discharged into the tank body 1 through the plurality of combing grooves 71. Due to the arrangement of the plurality of combing grooves 71, the overflow plate 7 has a comb-shaped structure, which can ensure that the room temperature pure water in the washing tray 2 can overflow into the tank body 1 quickly and evenly.

[0058] Reference Figure 1 A waste liquid inlet 14 is provided at one axial end of the tank body 1 , a waste liquid supplement inlet 15 is provided at the other axial end, and a waste liquid outlet 16 is provided at the lower side of the tank body 1 .

[0059] Reference Figure 1 The opening of the waste liquid inlet 14 allows the gas discharged from the electrolytic equipment and the waste liquid settled in the waste liquid to be directly discharged into the tank body 1, which allows a small amount of gas contained in the waste liquid to overflow from the waste liquid and finally be discharged from the gas outlet 12.

[0060] Reference Figure 1 The waste liquid replenishment inlet 15 is opened to replenish waste liquid into the tank body 1. On the one hand, since the addition of room temperature pure water will affect the concentration of the waste liquid, waste liquid can be added into the tank body 1 through the waste liquid replenishment inlet 15 to maintain the concentration of the waste liquid so that the waste liquid can be reused; on the other hand, since the waste liquid needs to pass through more equipment during the recycling process, the waste liquid is easily reduced due to leakage, and at this time, the waste liquid can be replenished through the waste liquid replenishment inlet 15.

[0061] Reference Figure 1 The waste liquid outlet 16 is provided to recycle the waste liquid and pure water at room temperature, and then after the waste liquid heat exchange and filtration process, the waste liquid can be returned to the electrolysis equipment.

[0062] Reference Figure 1 and Figure 2 , a liquid level gauge is provided in the tank body 1. In this embodiment, in order to optimize the effect of the gas scrubbing tank and improve the working efficiency of the gas scrubbing tank, the liquid level gauge controls the liquid level of the waste liquid in the tank body 1 to be 20% to 25% of the height of the tank body 1; the horizontal cross-sectional area of ​​the washing disc 2 accounts for 40% to 50% of the maximum horizontal cross-sectional area of ​​the tank body 1, and the distance between the upper side of the washing disc 2 and the top of the tank body 1 is not greater than 20% of the total height of the tank body 1.

[0063] The implementation principle of the embodiment of the present application is as follows: since the electrolysis equipment discharges waste liquid and gas at the same time, the waste liquid is discharged into the tank body 1 through the waste liquid inlet 14, and the tank body 1 realizes the storage of the waste liquid, and the small amount of gas contained in the waste liquid will automatically float out of the waste liquid. The gas is discharged into the gas pipe 3 through the gas inlet 11, and the gas is discharged into the washing disc 2 through the micropores on the gas pipe 3, and the gas continues to float upward out of the washing disc 2; at the same time, the spray component 5 sprays out room temperature pure water, and some room temperature pure water is also stored in the washing disc 2, then the gas will be fully in contact with the room temperature pure water to achieve gas washing. After washing, the room temperature pure water flows into the waste liquid in the tank body 1 through the drain hole 22 and the washing tank 21. During this process, the liquid level meter detects the liquid level of the waste liquid in the tank body 1 in real time.

[0064] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
